Stem cell research has yielded promising advances in regenerative medicine, but
standard assays generally lack the ability to combine different cell stimulations
with rapid sample processing and precise fluid control. In this work, we describe
the design and fabrication of a micro-scale cell stimulator capable of
simultaneously providing mechanical, electrical, and biochemical stimulation, and
subsequently extracting detailed morphological and gene-expression analysis on
the cellular response. This micro-device offers the opportunity to overcome
previous limitations and recreate critical elements of the in vivo
microenvironment in order to investigate cellular responses to three different
stimulations. The platform was validated in experiments using human bone marrow
mesenchymal stem cells. These experiments demonstrated the ability for inducing
changes in cell morphology, cytoskeletal fiber orientation and changes in gene
expression under physiological stimuli. This novel bioengineering approach can be
readily applied to various studies, especially in the fields of stem cell biology
and regenerative medicine.
